CUTTING MACHINERY.

Specification of Letters Patent.

Patented May 7, 1912.

Application filed July 1, 1910.' Serial No. 569,941.

To all whom t may concern Be it known that I, GODFREY l?. SCHMIDT, acitizen of the United States, residing at New York city, in the countyof New York and State of New York, have invented certain new and usefulImprovements in` Cutting Machinery, of which the following is aspecification, reference being had therein to the accompanying drawing.

My invention relates to improvements in cutting machinery and hasparticular reference to a machine adapted for use in cutting plasticmaterial such as chewing gum.

Referring to the accompanying drawings, Figure 1 is a side elevation ofa machine illustrating an application of my invention. Fig. 2 a planview of the same, and Fig. 3 an end view looking from right to left atFig. 1.

t is the base or support of the machine.

5 are angle irons or other suitable framework attached to the base t andproviding with said base support for the standards 6 serving as abearing for the shafts 7-7a upon which are mounted the sprockets 8MScarrying the chain 9. The shaft 7a is also provided with the ratchetwheels 10 adapted to be operated by the pawl 11 secured to the rockinglever 12 pivoted to the frame of the machine at 13. This lever 12 isoperated by the rod 14E connected therewith at 15 and connected to thecrank 16 by the pin 17.

18 is the main shaft preferably driven by a pulley such as 19. Upon thisshaft is also mounted the cam 20 and the ratchet wheel 21.

22 is another pawl secured to the frame-` work 23.

24 is a rocking shaft in the frame 23 supporting the levers 25, havingrollers 26 adapted to ride upon the cams 20 and provided with a slide 27adapted to depress the cutter 28 against the action of the spring 29which tends to keep the cutter elevated. Another lever' 30 is pivotallymounted on the framework 23 at 31 and is provided with a. roller 32adapted to ride upon the cam 33.

This lever 30 tends to drive the cutter 34C upwardly to meet thedescending cutter 28. The projections on the cams 20 and 33 arepositioned diametrically opposite so that it will be observed thecutters 28 and 34. approach and recede simultaneously, the cutter 2Sreceding under influence of the spring 29, and the cutter 34 underinfluence of gravity. It will also be observed that the motion of thechain 9 is intermittent, receiving its impulse from the pawl 11 pivotedto the rod 12 which is pushed forward each time the crank 16 turns withthe main shaft 18. The chain is also provided with a suitableapron'comprising strips 35 which are secured to the links in anysuitable manner as by the projections 36. The strips are preferablyformed with transverse grooves and are preferably spaced apart slightlyas shown by the spaces 36 so as to allow sufficient clearance for theknives 28 and 34 to cut the gum between the strips as it is fed throughthe machine.

Of course it will be understood that various modifications may be madewithout departing from the spirit of the invention as set forth in theclaims.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is:

1. In a machine of the class described, a framework and a pair ofsprockets thereupon carrying an endless chain, a driving shaft providedwith cams and a crank, a lever pivoted upon said frame and connected tosaid crank, and means in combination therewith for rotating one of saidsprockets, a pair of cutters adapted to travel in a guideway, a pair oflevers pivoted upon said frame and adapted to operate said cutters,means in combination therewith whereby said pair of levers are operatedby said cams.

2. In a machine of the class described, a framework and a pair ofsprockets thereupon carrying an endless chain, a driving shaft providedwith cams and a crank, a lever pivoted upon said frame and connected tosaid crank, and means in combinatently and said cutters operated aftereach tion therewith for rotating one of said time said sprocket-s arerotated. 10 sprockets, a pair of cutters adapted to travel In testimonywhereof I aHiX my signature in a guideway, a pair of levers pivoteclupon in presence of two Witnesses.
